摘要
We experimentally demonstrated a diode-pumped Kerr-lens mode-locked femtosecond laser based on an Yb：YAG ceramic. Stable laser pulses with 97-fs duration, 2.8-nJ pulse energy, and 320-mW average power were obtained. The femtosecond oscillator operated at a central wavelength of 1049 nm and a repetition rate of 115 MHz. To the best of our knowledge, this is the first demonstration of a Kerr-lens mode-locked operation in a diode-pumped Yb：YAG ceramic laser with sub-100 fs pulse duration.%@ 1674-1056
